HUMIDIFYING DEVICE Eon ovENs.

To all whom it may concern.'

Be it'known that We, DANIEL H. YOUNG and WILLIAM L. CAss, citizens of the United States, residing at Manchester, in the county of Delaware and State vof Iowa, have invented certan new and useful Improvements in Humidi'ying Devicesfor Ovens, of which the following is a specification.

Our invention relates to improvements in humidifying devices for ovens, particularly for bakers ovens, and the object of our improvement is to supply for bakers .use and for employment by anyone elsewhere the application is in anyway desired, means for quickly humidifying an inclosed space before and during the process of heating said space by other means, said` humidifyingl means being regulatable at will.

This object We have accomplished by the means .which are hereinafter. described andv claimed', and which are illustrated in the accompanying drawings, in which Figure 1 is a horizontal section of a part of an inclosure, such as an -oven o r the like, with ourimprovedv humidifyin'g apparatus 'installed therein; Fig, 2 is an=enlarged detail view, giving a longitudinal vertical section of the vaporizing chamber of said apparatus, with parts broken away; Fig. 3 is an enlarged.

' erspective view of portions of the parallel band electrodes and their supports, and Fig.

4,'i's an end elevation of the` regulatahle' liquid supplying-means for saidapparatus.

In said drawings, similar numerals of reference denote corresponding parts throughout the several views.

In Fig. 1 the numeral 28 denotes' part bf the structure of a vbakers oven or'any inclosure whose interior is to be humidified. A pipe 27 is carried across the interior of said oven and has one 'extremity passed' through one wall of the oven, the projecting end of the pipe being 'exteriorly threaded 'to receive 4a washer 25 and nut 26 to secure that end of the pipe to the oven-wall, the) end of the pipe also being' interiorly threaded to 'receive an eXteriorly threaded l plug 9. The other-end of said pipe is car- Speciication of Letters Patent.

ried through an opening in the opposite Wall of vthe oven, is similarly eXteriorly threaded to receive a washer 24 and a nut 23 to clamp it to the oven-wall. A T-coupling 1 is connected to this end of the pipe' by its limb 6, the opposite limb 7 being closed by means of a threaded plug 2. In-

directed limb 3 of said T-coupling is closed by a removable pluga made of `some insulating material, and centrally vertically oriced to permit the passage of an insulating tubel 14, through which are passed inseparatedrelation the pair of conductors 15 and 16, extending from some source of electrical current not shown. The extremities of said conductors within the T-coupling are connected to the ends of flat conducting bars or strips 18 and 17 respectively, said strips being carried throughout the length of the pipe'27 to terminate near the rear end of the latter.

To properly space the conducting strips 17 and 18 from each other by insulation and insulate them from said pipe, we pro-vide the V:tolle-wing spacing and supporting-means.

The numeral 19 denotes a cylindrical body 'of insulating material such as porcelain,

which has diminished and eXteriorly-threaded oppositely-directed extensions 21.-l Each conducting strip 17 and 18 iseircularly oriiced` at 22, with the orifics two strips, the cylinder 1 9 eingpositioned lbetween the strips, with the extensions -21 alined in the passed through said -alined orifices 22, and

the nuts 20 are placed on Vthe `extensions to hold the-strips tightly to the shoulders ofI said cylinder J19. This spaces the strips equally apart from each other` and at equal thestrips being provided `With as many of i distances from the interior wall of said pipe,

said supports as may be necessary to properly holdup the strips in constant parallel;

relation. Y

Referring'now to said F1gs.,l andai, 1n,

which the means are shown for furnishing a regulatable water-supply to the pipe 27, the numeral l2 denotes an invertedigtank delivering from its depending neck water, regulated by air-pressure in a Well-known way, to the receiver 13. A small conduit lOleads from said 4receiver 13 to said T-coupling 1, and contains a Valve-chamber 11 Whose valve is regulatable by a hand-wheel to adjustably cut-ofi' the water supply from the T-c'oupling and pipe. The apparatus shown is designed to maintain a water-level in the pipe 27 a little above the submerged strips 17 and 1Q and a little below the longitudinally-alined row of orifices 8 insaid pipe, the orifices preferably positioned somewhat below the upper wall of the pipe to deliver vaporous steam obliquely into the oven 28.

In the operation of the apparatus, the Water is first turned into` the pipe 27 to 'fill it tothe proper level, and thenan electric current at the proper voltage is passed through the conductors and the conducting strips, and since the strips are narrowly spaced and submerged, the current is passed through the intervening water, which quickly heats it to the boiling-point and almost instantaneously converts it into vapor or steam, discharging same into :the ovenv through .therowof small orifices 8. It will be seen that this eect is obtained regardlessfof the heatingl of the oven by other f means, and works. practically at once, so that when the oven is closed its' contained air is humidified from the beginning to a proper amount, thus correspondingly favoring the proper baking of the bread or other goods in the oven. The valve in said valve-chamber l1 can be used to shut oil' the water-supply when desired.

-The T-coupling '1, or other shaped chamber connected removably to an end of the pipe 27, has its large openings in the limbs 3 and7 provided for convenience in theNitroduction of a persons hands to connect or disconnect the electric connections therein,

and theremovable closures 2 and'4 therefore facilitate this.

- The apparatus shown may be modied in l 50 various particulars without de arting from the invention, and may be use to humidify other inclosures than ovens. v. [Having described our invention, what We claim as new, and desire to secure by'Letters Patent, is:
